Appendix D: Pictorial index to ncargex

The graphics shown in this appendix are the most descriptive frame of
each example available via the ncargex command. They
are shown here so you can quickly locate code that produces output
similar to what you need for visualizing your data.

To use this
index, scan all the graphics and note the names of examples that may
be useful to you. Working in an appropriate local directory,
execute:

ncargex example_name

where example_name is the name printed under the graphic. This
makes a local copy of the example source code, compiles and links the
source file(s), runs the executable, and produces an NCAR CGM (NCGM)
that you can examine with a viewer such as idt. For more
information, execute:

man ncargex
man idt

Many users supply their own data and modify the source code of these
examples as a shortcut to writing their own NCAR Graphics program from
scratch. A strategy for using this approach is outlined in one of the
chapters in this guide: Five quick
steps for creating and viewing your plot, see step 2.

Some examples have multiple frames, therefore, we suggest that you
view a particular example NCGM by using the ncargex command to
determine how well it might meet your needs.

The examples are
organized alphabetically by major utilities. Within the utilities,
the examples are arranged alphabetically. Some examples are duplicated
in more than one utility. For instance, the "cbex01" example
is located in both the Conpack and the Bivar sections because it is an
example of both. Click on any graphic below to see a list of all the
examples associated with that particular utility.
